The beginning and the end.

This creation differs greatly from our previous preamplifiers and overdrives: it is fully operational amplifier based and has two distinct distortion circuits (Alpha and Omega) which can be selected or blended using our Mod knob. This unusual control, in conjunction with the toggle switches and 3 active band equalizer makes Alpha · Omega the most flexible among our designs.

Front Features
Blend

Mixes the clean and processed signals. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine mix tuning.

Level

Sets the volume of the overdriven signal.

Drive

Sets the amount of gain in the overdriven signal.

Bite

Boosts High Mids (2.8kHz) for additional presence and definition.

Growl

Shelving Bass Boost for a fatter tone and increased low end saturation.

Mod

Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of definition, whereas Omega is simply brutal and raw.

Bass

+-12dB @ 80Hz

Mid

+-12dB @ 500Hz

Treble

+-12dB @ 5kHz

Input & Outputs
Output

Connect from the ¼” Output jack to the input of your amplifier or another effects pedal.

Ground Lift

Use this control to lift the ground of the XLR output. If you are experiencing ground noise in your DI signal, try changing this control.

Direct Output

A balanced version of the ¼” output, useful for running into PA’s or studio mixing consoles. 

Input

Connect your instrument or output from your pedal board to the ¼” mono jack.

9V DC

Only use a regulated 9V DC adapter with a center-negative plug.

Parallel Output

A passthrough for your input signal, useful for parallel processing.
